Driving Features

Schedule

Given the changes required for the above features and the given
schedules, Release Engineering will be ready to start scripted rebuilds
on Thursday, February 3rd. All automated rebuilds should be finished prior to the Feature Freeze.
Any clean-up manual rebuilds should be finished prior to the Alpha Change Deadline.

Scripts

Release Engineering has created two scripts. One is to initiate the builds, and the other is to query for items still needing to be built.

Build Initiation

Generate a list of all packages in f24
Loop through each package:
Query if a build has already been attempted/completed since koji changes went live.
If so, move to next package
If not, check out git
rpmdev-bumpspec
fedpkg commit -cp
fedpkg (background) build
Move on to next package

Each step will have some error catching and logging so that people
can clean up the various failures for whatever reasons. The builds will
be background builds, which will allow other builds done to take higher
priority when a builder has a free slot. However maintainers should
take care when doing this so that the background build won't take
'latest' precedent when it finishes. Asking rel-eng to kill the
scripted build will typically be enough.

Build Tagging

Once the rebuild script has finished, another script will run to tag the builds into f24. This script will check that a newer build hasn't been done or started in f24 since the scripted rebuild was submitted. This will protect against the scripted rebuild overriding an even newer build done while the scripted rebuild was waiting in the background.

Status Query

Release Engineering has developed a script to query f24
and report on packages that have yet to be rebuilt. Results of these
queries will be delivered to various places, yet to be determined,
broken down by maintainer for easier discovery of work needed.

Maintainer Actions

Maintainers should ensure that their packages currently build from source.

Maintainers should ensure that there are no unwanted changes committed to git but not built yet.

Frequently Asked Questions

When will my own build "count" for the rebuild?

After the last piece needed for thee mass rebuild a gcc build was put into place, a build done by a maintainer will "count" toward the rebuild. 2016-02-02 10:30:08 is the UTC time that builds count from

Will the rebuilds be ordered?

Currently there is no plan to logically order the rebuilds based on deps. The ordering will be alphanumerical based on package name. There are no planned ABI/soname changes that would require logical build ordering. Further, all the builds will be kept in a special tag (f24-rebuild) until the whole run is done, and then they will be tagged into f24 in one shot to minimize the shuffle of buildroot contents during the rebuilds.
